I enjoy the work of Charles Yu. I liked his first collection of stories, Third-Class Superhero, and his novel, How to Live Safely in a Science-Fictional Universe, for their New Yorker-meets-quantum physics style. There's something inherently funny and interesting about the combination of worrying about marriages, employment, and family ties in the context of time travel, space travel, and alternate universes. That said, the well runs a bit dry in Sorry Please Thank You. About half of the stories are brilliant and funny or heartbreaking or both. "Yeomans," about what a "red-shirted ensign" in a Star Trek-like universe goes through knowing the yeoman always dies, is the best story in the lot, but there are clever and affecting stories all the way through. "Hero Absorbs Major Damage" is a fascinating and fully realized look at a video game from another perspective. The other half of the stories, however, in particular "Human for Beginners," just ramble on and on, throwing in a quantum physics buzzword here, a Trek-type reference there, but all in the service of... not much. ("Human" is especially galling in its use of pagination tricks to pad out its already-interminable length.) I think it was just too soon for another collection of Yu's stories -- there aren't enough good ones to make it completely worthwhile.
